/*
|
|
* This is a regular expression library that implements a subset of Perl RE.
|
|
* Please refer to http://slre.sourceforge.net for detailed description.
|
|
*
|
|
* Usage example (parsing HTTP request):
|
|
*
|
|
* struct slre slre;
|
|
* struct cap captures[4 + 1]; // Number of braket pairs + 1
|
|
* ...
|
|
*
|
|
* slre_compile(&slre,"^(GET|POST) (\S+) HTTP/(\S+?)\r\n");
|
|
*
|
|
* if (slre_match(&slre, buf, len, captures)) {
|
|
* printf("Request line length: %d\n", captures[0].len);
|
|
* printf("Method: %.*s\n", captures[1].len, captures[1].ptr);
|
|
* printf("URI: %.*s\n", captures[2].len, captures[2].ptr);
|
|
* }
|
|
*
|
|
* Supported syntax:
|
|
* ^ Match beginning of a buffer
|
|
* $ Match end of a buffer
|
|
* () Grouping and substring capturing
|
|
* [...] Match any character from set
|
|
* [^...] Match any character but ones from set
|
|
* \s Match whitespace
|
|
* \S Match non-whitespace
|
|
* \d Match decimal digit
|
|
* \r Match carriage return
|
|
* \n Match newline
|
|
* + Match one or more times (greedy)
|
|
* +? Match one or more times (non-greedy)
|
|
* * Match zero or more times (greedy)
|
|
* *? Match zero or more times (non-greedy)
|
|
* ? Match zero or once
|
|
* \xDD Match byte with hex value 0xDD
|
|
* \meta Match one of the meta character: ^$().[*+?\
